I have had an intake in my Cavalier for a few years now and like the HP increase. After the install on the Trailblazer I instantly felt the increase in HP and the sound from the engine compartment wasn't that loud at all.
I have noticed about a 1-2 mpg increase for the tank of gas that i ran after the install so that's a bonus for me since I run about 250 miles a week commuting to work and back.
Installation wasn't that hard, the directions that are provided are straight forward and easy to understand. The K&N uses existing bolts and holes so swapping back to stock is a breeze with the exception of cutting the air return hose. I had an extra hose from a previous repair so i'm not concerned about that.
Overall I love my intake and would recommend it to anyone.

It took me about 2 hours to install but did fit very nice.I like the look of it. If you drive normal, it is still quiet but as soon as you get heavy on the pedal, you can hear the difference. I haven't noticed yet if it is helping the M.P.G.

"I have a 4.2 inline 6 in an 07 Trailblazer. As soon as I installed the intake, you could notice a dramatic difference in the response with very light acceleration. It is taking a week or so for I think the computer to get used to the increased volume of air and I have not had a normal gas tank of driving yet, but the gas mileage is now seemingly increasing. I really noticed the difference in power when towing the boat and the mileage seemed to be better. Just for the driveability pleasure, the item is well worth it. Install took about an hour and was easy to do." —Dean A from Pearland, TX bought a K&N 63 Series AirCharger High-Flow Intake Kit for a 2007 Chevy Trailblazer, 4.2L 6-cyl. engine.

"I have installed after-market air filters on my vehicles for a number of years. This application on a 2007 5.3L V8 Trailblazer redefined tight fit. The clearance between the bottom of the actual filter and the area where the stock box had been installed was minimal. A part description was supplied, no
directions. The finished product seems to function well.
K&N is much more user friendly. Installation time 40 minutes most due to the bottom clearance issue." —Lewis W from Northford, CT bought a Volant Cold Air Intakes for a 2007 Chevy Trailblazer.

"This intake gave me over 300 horsepower on my truck, so when I barely put dowm the gas all the imports get embaressed, especially FORD'S. It was real easy to install it took me only 20-25 minutes. Sounds like a beast when the throttle goes dowm.... Great job keep up the good work!!!!!" —Shirley G from Hopewell, VA bought a K&N 63 Series AirCharger High-Flow Intake Kit for a 2007 Chevy Trailblazer.
